Pasta Shells With Portabella Mushrooms and Boursin Sauce

There’s something incredibly comforting about a creamy pasta dish, especially when it’s infused with earthy mushrooms and that distinctive Boursin flavor. I remember my first attempt at making this recipe – I was in college, homesick, and desperately craving something familiar. The rich aroma of the sautéed mushrooms filled my tiny apartment, instantly transporting me back to my mom’s kitchen. Even though I slightly overcooked the pasta that first time, the velvety sauce and savory mushrooms made it an instant favorite. It’s a dish that always feels like a warm hug, and one I’ve tweaked and perfected over the years.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 4
• Dietary Type: Vegetarian

Ingredients

• 1 tablespoon butter
• 1 tablespoon olive oil
• 1 lb portabella mushrooms, stems removed, caps halved and then cut into 1/4-inch slices
• 1/2 teaspoon salt
• 1/4 teaspoon pepper
• 1/4 cup white wine
• 1 teaspoon minced garlic (from a jar works)
• 1 1/4 cups chicken broth (preferably low-sodium)
• 5 1/2 ounces pepper Boursin cheese (garlic and herb also works if pepper is unavailable)
• 1 lb asparagus (broccoli or sugar snap peas are also good choices)
• 3/4 lb medium pasta shells
• Grated parmesan cheese, to taste

Equipment Needed

• Large frying pan
• Small saucepan
• Large pot

Instructions

1. Begin by prepping the asparagus. Snap off the tough ends of the asparagus spears and discard them. Cut the remaining spears into 1/2-inch pieces.
2. In a large frying pan, melt the butter together with the olive oil over medium heat. This combination of fats helps to prevent the butter from burning and adds a richer flavor.
3. Add the sliced portabella mushrooms to the pan and cook, stirring occasionally, until the mushrooms are tender and well browned, approximately 6 minutes. Don’t overcrowd the pan; if necessary, cook the mushrooms in batches to ensure proper browning.
4. Stir in the salt, pepper, and minced garlic. Stir to combine and reduce the heat to medium-low. The garlic will become fragrant quickly, so watch carefully to prevent it from burning.
5. While the mushrooms are cooking, prepare the Boursin sauce. In a small saucepan, heat the chicken broth until it is lightly boiling.
6. Add the Boursin cheese and white wine to the simmering chicken broth, stirring with a fork to help the cheese melt and incorporate smoothly. Lower the heat to a simmer to allow the sauce to thicken slightly. If you’re not using pepper Boursin, add 1/4 teaspoon of black pepper to the sauce.
7. Once the cheese is fully melted and the sauce has thickened, pour the sauce into the frying pan with the cooked mushrooms. Stir to combine and allow the mixture to simmer gently.
8. In a large pot of boiling, salted water, cook the pasta shells until they are almost done, about 6 minutes. Remember to reserve about 1 cup of pasta water before draining, just in case your sauce needs a little loosening up later.
9. Add the chopped asparagus to the pot with the pasta and cook until both the asparagus and the pasta are just done, about 3-4 minutes longer. The asparagus should be tender-crisp. If using broccoli, add it with 2 minutes left to go; if using sugar snap peas, add them with about 1 1/2 minutes remaining.
10. Drain the cooked pasta and asparagus thoroughly.
11. Add the drained pasta and asparagus to the frying pan with the mushroom and Boursin sauce. Toss to coat everything evenly, ensuring that the pasta is well-covered in the creamy sauce. Season to taste with additional salt and pepper, if needed.
12. Serve immediately, garnished with grated Parmesan cheese.

Expert Tips & Tricks

• For a deeper, richer mushroom flavor, consider using a mix of mushroom varieties, such as shiitake or cremini, in addition to the portabellas.
• To prevent the Boursin sauce from separating, be sure to keep the heat low while it simmers. If the sauce becomes too thick, add a splash of the reserved pasta water to thin it out.
• If you want to add a protein to the dish, grilled chicken or shrimp would be excellent additions.
• To elevate the presentation, garnish with a sprinkle of fresh parsley or chives.

Serving & Storage Suggestions

Serve this pasta dish immediately for the best flavor and texture. The creamy sauce is at its peak when freshly made.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a saucepan over low heat, adding a splash of milk or chicken broth to loosen the sauce if necessary. This dish is best enjoyed fresh, as the pasta can become slightly soft upon reheating. Freezing is not recommended, as the sauce may separate upon thawing.

Variations & Substitutions

• For a gluten-free version, use your favorite gluten-free pasta shells.
• To make this dish vegan, substitute the butter with olive oil or vegan butter and use a plant-based cream cheese alternative instead of Boursin. Nutritional yeast can be added for a cheesy flavor. Also ensure the “chicken” broth is replaced with vegetable broth.
• Experiment with different vegetables depending on the season. Roasted bell peppers, zucchini, or spinach would all be delicious additions.
• For a spicier kick, add a pinch of red pepper flakes to the sauce.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of cheese if I can’t find Boursin?
A: While Boursin provides a unique flavor profile, you can substitute it with Alouette cheese or goat cheese mixed with garlic and herbs.

Q: Can I make this dish ahead of time?
A: It’s best to serve this dish immediately after cooking, but you can prepare the sauce ahead of time and store it in the refrigerator for up to 2 days. Just cook the pasta fresh when you’re ready to serve.

Q: Is it necessary to use low-sodium chicken broth?
A: Using low-sodium chicken broth allows you to control the saltiness of the dish. If you use regular chicken broth, be sure to taste and adjust the seasoning accordingly.

Q: Can I add meat to this recipe?
A: Absolutely! Grilled chicken, shrimp, or Italian sausage would all be excellent additions to this pasta dish.

Q: How do I prevent the pasta from sticking together after it’s cooked?
A: Be sure to cook the pasta in plenty of salted water and drain it immediately after it’s cooked. Toss it with a little olive oil or the sauce to prevent it from sticking.
